Title: Maf conversion from hitachi to Bosch Post by: S4addict on September 04, 2014, 06:41:57 AM hello all ive looked and re checked my looking to make sure i just wasent over looking something simple i could of read.
im trying to convert my hitachi file to a bosch maf and have come up blank on info of how to do so other then setting the MLOFS 0 value to 200 on the tune. now im asuming i need to scale it again since ive changed the offset, or is scaling the maf only changed when you use a bigger housing? also the file is an mbox so its six speed hatachi maf and has esp. if i try and run it on a 2000 s4 six speed with the maf change. the only thing next to worry about is the esp switch correct? any info is much appreciated. thank you Title: Re: Maf conversion from hitachi to Bosch Post by: stuklr on September 04, 2014, 08:03:46 AM Scaling is for larger housings.

Title: Re: Maf conversion from hitachi to Bosch Post by: nyet on September 04, 2014, 01:25:52 PM MLHFM and KFKHFM also have to be changed Yep. Even with the same housing, MLHFM is different between bosch and hitachi. See S4 551A vs 551M (for example). Historically, people have gotten away with not copying over MLHFM, but it is "wrong" enough that it is advisable to copy it. KFKHFM is debatable, though. That seems to be more dependent on airbox configuration than MAF YMMV.
